Abstract

In this paper, we describe the Sketched Menu, a menu technique for launching Graphical User Interface (GUI) objects in a tabletop interface. The Sketched Menu enables the user to define interactively the shape, size, orientation, and location of a new GUI object before it is launched. These parameters are specified implicitly by the user via a shape drawing. The shape corresponds to a simplified outline of the object. A menu for the given shape is launched at the exact location of the drawing and the user can then select the desired graphical object or application. A laboratory experiment was conducted to compare this new menu technique with the traditional pop-up-menu approach. The results show that the time to create an object and the positioning accuracy are similar for the two techniques. There are two advantages to using the Sketched Menu. Firstly, graphical discontinuities are avoided when adding objects to the interface. Secondly, because the object appears exactly in the desired location and orientation, it does not hide other graphical objects, thereby reducing disruption to other users' tasks.
